Answer:

CHO₂

Explanation:

The following data were obtained from the question:

Carbon (C) = 26.68%

Hydrogen (H) = 2.24%

Oxygen (O) = 71.08%

Empirical formula =?

The empirical formula of the compound can be obtained as follow:

C = 26.68%

H = 2.24%

O = 71.08%

Divide by their molar mass.

C = 26.68 /12 = 2.223

H = 2.24 / 1 = 2.24

O = 71.08 / 16 = 4.4425

Divide by the smallest.

C = 2.223 / 2.223 = 1

H = 2.24 / 2.223 = 1

O = 4.4425 /2.223 = 2

Thus the empirical formula of the compound is CHO₂

If 1.45 moles of Sodium Bromide are added to a 7.5 M solution, what is the volume of the solution made?
timurjin [86]

Answer:

0.193 L

Explanation:

Another way of writing the question would be: What volume of a 7.5 M Sodium Bromide solution would contain 1.45 moles.

To answer that we can use the <em>definition of molarity</em>:

  • Molarity = moles / liters

We <u>input the given data</u>:

  • 7.5 M = 1.45 moles / liters

And <u>calculate how many liters are required</u>:

  • 1.45 mol / 7.5 M = 0.193 L
